As David begins his reign, he writes a song of personal grief. David grieves the loss of Saul and Jonathan. He remembers past days of faithfulness as the king and the nation walked in faithfulness to God and knew His blessing. He also grieves what has been lost in disobedience and sin. Saul started off so well but sin ate his latter years. Sin and disobedience took away his opportunity to reign. Sin took his son to death. Sin took the army into defeat and sin ultimately cost him his life. Sin always costs us more than we want to pay. Sin matters. And this lesson must be taught to the nation. That’s why David will make it a national song of lament. A song to be taught to their children. Why? Because David knew as the old saying goes, “Those who do not learn history are destined to repeat it.”
